We patched up a few things in the latest update. Here's what's new in Version 1.0.3:

We realized the Buttercup Would Be Proud achievement might be a little too brutal, so we loosened the requirement to 5 saves instead of 3. (If you have beaten Hardcore Mode with 5 or fewer saves, and you still have that game file, you should be awarded this achievement on your next game start.)

Buttercup's hair needed a bit of a makeover in Classic Mode.

We adjusted the Classic Mode background graphics and rendering pipeline for an improved look and feel.
